Certain businessmen who have the power to control civilization on a large scale. It's probably like a pyramid where only the top ones own the privilege to actually issue money, give orders to and influence governments, start wars, create and spread diseases etc. The less control one has in the pyramid, the less they know as well. As for whether these people are the infamous Illuminati or something else, I have no idea. But going by just observing how human hierarchic systems work, the above seems likely.
The ones who are known by their names are probably quite low rank in the pyramid, including Musk, Soros, Hollywood producers or politicians. And even they have tremendous power.
These people have above average intelligence, but not highly gifted, they are not near genius level. They are in the zone of
Cluster B personality disorders, and are probably bored as well.
